Management techniques to reduce infection with chalkbrood include keeping hives clean, replacing storage and brood combs regularly, and keeping hives well ventilated and dry.

Management practices which may reduce the effects of chalkbrood disease are:

1. removing ‘mummies’ from bottom boards and around the entrance.
2. destroying combs containing large numbers of ‘mummies’
3. supplying new combs.
4. providing good ventilation in hives.
5. adding young adult bees to hives.

Chalkbrood disease is caused by the fungus Ascosphaera apis. The fungus produces spores which are swallowed by honey bee larvae when they are fed by nurse bees. The spores germinate in the honey bee’s gut and ultimately cause the larvae to die of starvation.

This adds up to many, many hours, especially in the early spring when fruit trees need attention. A second major difference between honey bees and mason bees is their taste for sugar. Since honey bees must make honey, they seek out nectar that is very high in sugar.

There are many different kinds of Masonry Bee in the UK, but all can cause damage to structures. Although these bees are considered solitary, they do seem to re-nest in the place they developed, meaning that populations remain in place for decades.

Do masonry bees cause damage? Yes, they do. The holes they create may cause some problems in a structure and allow moisture to penetrate into the material and cause further damage. This is especially true if more than one nesting hole can be seen adjacent to one another in a small area.

The spread of sacbrood is believed to be caused by feeding young larvae contaminated pollen, nectar or water. Nurse bees become infected with the virus while cleaning out cells containing diseased larvae.

Chalkbrood (Ascosphaera apis) is a fungal disease affecting honey bee brood. As in AFB and sacbrood, the disease kills brood in the late larval (prepupal) stage, when the larva has laid out fully along the bottom wall of the cell.

Chalkbrood is a fungal disease called Ascosphaera apis that affects the gut of the bee larva. The fungus starts in the gut of the larva and competes for the larva’s food causing the larva to starve.

Masonry bees are so called because they enjoy living in nests made from soft materials. If your mortar is in good condition, you shouldn’t experience any problems with masonry bees. However, if left to their own devices, these bees can cause structural issues that could well be expensive to fix.

Navigate / search. Chalkbrood is a fungal disease of honey bee brood that infects the gut of the larvae. It is caused by a spore-forming fungus named Ascosphaera apis that is consumed along with larval food.

Larvae become chalk-white and are often covered with cottony filaments. The white coloration may eventually give way to a gray or black, depending on the life stage of the fungus. It often appears at the perimeter of the brood nest. Infected or dead larvae may be seen at the hive entrance or in pollen traps.

Monodontomerus: Lay their eggs inside the cocoon of the the mason bees. These pests are a primary concern for exposed cocoon releasing. It is easy to tell if Monodontomerus has affected a cocoon because There will be multiple larva inside the cocoon.

Cleaning cocoons keeps parasite numbers low and prevents disease spread in the colony. Washing cocoons and the bee house removes pollen mites, parasitic wasps, dermestid beetles and fungal pathogens that feed on pollen, nectar and developing bees.
